SPECIFICATION formingpart of Letters Patent No. 658,478, dated September25, 1900;

Application filed February 15, 1897. Renewed March 6, 1900. Serial No.75593- (Model.)

T0 Ml whom it may concern:

Be it known that we, HARVEY D. WIL- LIAMS, residing at Ithaca, in thecounty of Tompkins and State of New York, and HOR- ACE G. HOADLEY,residing at W'aterbury, in the county of New Haven and State ofConnecticut, citizens of the United States of America, have invented acertain new and useful Improvement in Mechanical Movements, of which thefollowing is a description, reference being had to the accompanyingdrawings, wherein Figure 1 is what may be called an elevation view whenthe main rotary shaft is held in a vertical position. Fig. 2 is anotherelevation View from the point A. Fig. 3 is a sectional detail.

The object of the improvement is, in general terms, to produce therotary movement of a shaft by means of the vibratory movement of a levervibrated in a plane embracing the axis of said shaft as well asotherwise.

In the accompanying drawings, the letter a denotes the rotary shaft. Theletter I) denotes two ratch-wheels fixedly attached to said shaft. Themechanism is operative if only one ratch-wheel is used, but itsefficiency is practically doubled by the use of two'.

The letter 0 denotes two oscillatory pawls each cooperating in actionwith one of the ratch-wheels.

The letter (Z denotes two supports, one for each of the pawls, journaled on said shaft and each carrying its pawl c.

The letter e denotes two similar curved yokes, each of which ispivotally attached to one of the pawl-supports. Both are brought to acommon pivotal attachment and there the operating-lever f is attached.

The letter g denotes a frame or handle for supporting and holding therotary shaft journaled on the latter.

By vibrating the lever f back and forth in any plane embracing the axisof the shaft or any path, curved or straight, approximating to such aplane the pawls alternately give the ratch-wheels, and consequently themain shaft, a step-by step rotary motion.

One purpose to which this improvement is readily applicable is theoperation of a handdrill.

The foregoing specification has mentioned and described ratch-wheels andcooperating pawls. Any frictional device which can be substituted forthe ratch and pawl is the mechanical equivalent thereof.

WVe claim as our improvement l 1. In combination, the rotary shaft, aratchet-wheel fixed upon said shaft, a curved support journaleduponsaidshaft and carrying an oscillatory pawl cooperating with saidratchet-wheel, a second curved support, and curved yokes pivotedrespectivelyto said pawlsupports and joined bya common pivotalattachment, whereby the movement of said common pivotal attachment inany path approximating to an axial plane of said shaft causes theoscillation of said pawl and the intermittent rotation of said shaft,substantially as shown and described. v

2. In combination, the rotary shaft, the two ratch-wheels fixed on saidshaft, the two oscillatory pawls, the two supports for said pawlsjonrnaled on said shaft, and the two connecting-rods each pivotallyattached to one of said supports and brought to a (30111-- mon pivotalattachment to each other, all substantially as described and for thepurposes set forth.
